CAR-TRUCK.

To all whom it may concern:

Be it known that I, EDWARD POSSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Trucks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Generally stated, this invent-ion relates to and has for its object toimprove the construction of car trucks, and to such ends, the inventionconsists of the novel devices and combinations of devices hereinafterdescribed and defined in the claims.

More particularly and specifically stated, my invention is directed tothe improvement of truck side frames of the arch bar type, and. has forits object the elimination of castings and of bolts in the side frameproper, and a resulting increased strength and durability in thecompleted truck frame.

These objects and others are accomplished in the improved truck, thepreferred embodiment of which is illustrated in the accompanyingdrawings. In this preferred form of the truck frame, no castings areemployed, pressed steel or wrought iron elements being substitutedtherefor. All of these parts are rigidly connected by rivets, and allbolts are eliminated from the side frame proper, the only bolts employedin connection therewith being the journal box bolts.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation showinga truck frame designed in accordance with my invention; Fig. 2 is a planview showing one side of the truck frame; Fig. 8 is a fragmentary viewin perspective, some parts being sectioned on the line 02 m on Fig. 1;Fi 4 is a fragmentary view in perspective, some parts being sectionedapproximately on the line 50* as" on Fig. 1; and Fig. 5 is a fragmentaryview in perspective, some parts be- Specification of Letters Patent.

ing sectioned approximately on the line as w on Fig, 3.

The numerals 1 and 2 indicate, respectively, the top and bottom archbars, the numeral 3 the journal boxes and the nume 'al 4 the wheels of atruck of the arch bar type. Tie straps 5 are riveted at their inner endsto the bottom arch bar .2 and are extended under the journal boxes.Customary journal box bolts (3 are used to clamp the journal boxes tothe overlapping endsof the arch bars 1 and 2, and to the undcrlyil'igends of the tie straps 5.

In place of the usual cast columns, I employ steel or wrought ironcolumns 7 that are pressed or rolled into channel form, and at theirupper and lower ends are lapped or bent around the top and bottom archbars,

respectively, so that, preferably, they completely embrace the same. Thebest possible connection between the sand columns and arch bars is madeas follows: The upper ends of the columns 7 are slit at their angles(these slits being preferably made before the columns are bent intochannel form), and the upper ends of their webs or intermediate portionsare turned backward to form flanges 8 that bear directly against theinner surface of the top arch bar 1. The extended upper ends 9 of theside flanges of the said columns are then bent, one over the other andover the top of the arch bar 1, so that they tightly embrace the saidtop arch bar. Very much the same thing is done at the lower ends of thecolumns, that is, they are slit at their angles, (preferably before thecolumns are bent into channel form) and the lower ends of their webs areturned backward to form foot flanges 10 that rest directly upon theupper surface of the bot tom arch bar 2, and the lower ends 11 of theside flanges of said columns are bent, one over the other, and lappedaround and under the said bottom arch bar in close contact therewith.Rivets 12 are passed through the top flange 8, through the top arch bar1, and through the overlapped upper ends 9, and other rivets 1.3 arepassed through the extended ends of the said flanges 8 and through thetop arch bar. Rivets 14: are passed through the foot flange 10, throughthe bottom arch bar 2 and through the over lapped lower ends 11 of thecolumns. The lower ends of the columns 7 are preferably offset outwardlyat 7 for a purpose which will presently appear. Channel -shaped pressedsteel or wrought iron column bases 15, are seated on that portion of thebottom arch bar 2 that extends between the columns, and the webs of theupturned ends of-these column bases engage directly with the faces ofthe offset lower portions of the said columns. Angle iron or steel crosstransoms 16 are seated in the angles of the column base 15 and rivets 17are passed through their horizontal flanges, through the said columnbase and through the bottom arch bar 2.

Chafing plates 18, pressed or rolled into channel shape, are placed onthe inner faces of the columns 7 and are secured thereto by rivets 19.The side flanges are cut ofl from the lower ends of these chafing plates18 and these depending ends are overlapped with the vertical flanges ofthe angle transoms 16. Centrally located rivets 20 are passed throughthe lower ends of the chafing plates 18, through the upturned flanges ofthe angle transom 16, through the upturned ends of the column base 10,and through the webs of the cooperating columns 7, thus rigidly unitingthe said parts. Other rivets 21 are passed through the lower outer edgesof the said chafing plates, through the upturned flanges of the angletransom 16 and through the webs of the upturned ends of the said columnbase 10. Here, it may be noted that the columns 7 are but slightly widerthan the arch bars 1 and 2, being only sufficiently widened to cause thevertical flanges thereof to straddle the said arch bars. The columnbases 10 and the chafing plates 18 are preferably of the same width andboth are considerably wider than the said columns. The upper ends of therivets 17 are preferably countersunk into the horizontal flanges of theangle transom 16 so as to afford a smooth bearing for the spring bases,not shown. Also, the inner ends of the rivets 19 are preferablycountersunk into the faces of the chafing plates 18, so as to affordsmooth bearing surfaces for the truck bolster, not shown. Secured to theupper portions of the inner flanges of the chafing plates 18, are breakhanger brackets 22, shown as formed by steel or wrought iron plates bentinto channel-shape form. The inner and outer flanges of these hangerbrackets 22, and the inner flanges of the chafing plates 18, to whichthey are riveted, are provided with alined perforations 23 through whicha bolt pin may be passed to attach the break hanger links.

The arch bar truck frame illustrated is of the Master Car Builders type,but so far as my invention is concerned, may be much altered. I believeit to be broadly new and desire to claim broadly any kind of a truckframe in which columns are provided with end flanges or portions bent toembrace the arch bars and thereby interlocking the said columns and archbars independently of rivets. The rivets are, of course, necessary togive the desired strength and rigidity, but additional and independentstrength is given by lapping the ends of the columns with the arch bars.Also, the manner of forming and connecting the column bases to thecolumns, to the lower arch bar,'and to the transoms, is consideredbroadly new. Further, novelty is added by the application of the chafingplates and the manner of connecting the same to the columns, crosstransoms and column bases. This arrangement gives a maximum loadcarrying capacity in the truck frame with a minimum of material, and atthe lowest possible cost of construction. In the truck side framesproper, there are no bolts, and hence, no joints that can work loose,and the rivets, when properly applied, connect the truck elements asrigidly as if they were integrally united. The channel-shaped columnbases, in addition to other functions, prevent the load from deflectingthe bottom arch bar between columns, and they also aflo-rd a wide baseto which the angle transom may be riveted.

One object of this invention is the provision of a multi-part pressedsteel or wrought iron truck frame to displace steel castings. These sideframes, complete, ex cept the journal boxes, or with the journal boxesapplied for that matter, but without the transoms applied, can be builtand shipped, and the cross transoms applied at the place and by thepersons completing the erection of the trucks.
